Title: Error concealment in digital television signals
Inventor: COLLINS MARK CHRISTOPHER
IPC: H04N5/94
Filed: 1982-05-14
Abstract: A method of concealing errors in a digital television signal formed by a plurality of sample signals corresponding respectively to sample positions S-3, S-2, S-1, S0, S1, S2, S3, etc. along a horizontal scan line of a television picture made up of a plurality of such lines n-1, n, n+1, etc., the method comprising, in respect of each sample signal which is in error, selecting from a plurality of algorithms a preferred algorithm for correcting the error sample signal, calculating a corrected value of the error sample signal using the preferred algorithm, and substituting the corrected sample signal for the error sample signal so as to conceal the error. Where any algorithm involves the use of an error sample, that algorithm is not used. The algorithms may be twelve in number and use sample values located along four directions A B, C and D respectively of the television picture to predict the known sample values at sample positions adjacent to the position of the error sample signal, the direction corresponding to the algorithm giving the best result being selected.

Title: A device for controlling the level of liquid
Inventor: ALTMANN JOSEF
IPC: F28F27/00
Filed: 1982-07-23
Abstract: The liquid level in a vessel (3) e.g. a condensate collecting tanks controlled by a valve (6) in the outlet conduit (61) operated by a hydraulic servodrive (5). The control means include a sensing tank (2) communicating with a fluidic sensing unit (1) which communicates, via a control pipe (51), with the hydraulic servodrive (5). The pressure applied by the unit (1) varies according to the liquid level in a sensing tank (2). The tank (2) is connected to an annular space (41) communicating with the throat of a venturi nozzle (4) in the outlet conduit (61). Whereby the level in the sensing tank is dependant both on the liquid level in tank (3) and the flow rate from that tank. If the level in tank (3) increases, the difference in levels between the tanks  DELTA H falls causing a reduction in flow through pipe (22). The level in tank (2) rises causing the pressure from unit (1) to valve (5) to drop and valve (6) to open. <IMAGE>

Title: An electronic control system for heating systems
Inventor: MACHARG JAMES ADRIAN
IPC: F23N1/00
Filed: 1983-12-02
Abstract: An electronic control system for a boiler in which a timer (TD1) interrupts and reconnects the power supply to the boiler via a relay L and contacts L:1. A capacitor C3 memorizes the period for which the thermostat (TH) associated with the boiler is "off", the capacitor being slowly discharged during the thermostat "off" periods by a presettable variable resistor (VR1) and a resistor (R4). The duty cycle of the timer (TD1) is varied by the charge on a capacitor (C5) which is charged through a transistor (TR2), the base of which is biased according to the state of discharge of the memorizing capacitor (C3). In order to over-ride the effect of a long thermostat "off" period, when the system demands more heat due to sudden heavy usage, a Schmidt trigger (TD2) recharges the memorizing capacitor (C3) when triggered by the charging of a capacitor (C7) above the threshold value of the Schmidt trigger. The boiler is effectively pulsed during the thermostat "on" periods, the duty cycle of the pulses being determined by the state of charge of the memorizing capacitor (C3). <IMAGE>
